What are photoselective meshes OBAMALLA®?
It is a tool that OBAMALLA® specifically modifies the spectrum of filtered light in the ultraviolet regions. And intensifies diffuse radiation and also affects the thermal components of the crop. You can vary the shading from 5% up to 95%. The mesh that makes Raschel type is treat with an additive against ultraviolet rays. And the structure allows crop protection during stress conditions.
The photoselective mesh is an agricultural practice that is use as aluminized. Which serves to create greater refection and a diffused light effect under the fabric. Photoselective meshes are based on various chromatic additives, light scatterers and reflective elements within the mesh materials. These materials select various spectral components of solar radiation such as UV and PAR radiation. Or transform direct light into diffuse light.
Plant effects.
effects on plants of modified sunlight conditions, especially the increased proportion of blue wavelengths and the aluminous spectrum, have be investigate.
of modified sunlight conditions, especially the increase in the proportion of blue wavelengths and the light spectrum in relation to the accumulation of AC in two species of Vaccinium. (berries) was investigated: the European wild blueberry. (V. myrtillus L.) and the cultivated Highbush blueberry (V. corymbosum L., cv Brigitta Blue).
results showed a significant increase in productivity under the photoselective nets, highlighting that the number of fruits produced per plant throughout the growing season was 30% to 40% higher, and the yield was 20% to 30% higher under photoselective meshes.
Red Shadow Mail
In the case of the red mesh, it help to prevent the passage of the blue bands, so the proportion of red light that reach the plants was increase, UV-A and UV-B radiation were reduce. They also repeatedly increased the productivity of leafy crops, peppers and ornamentals, each compared to a standard cover. . The effect of the nets was compare to plants grown under sunlight in the open field without any type of screen. Near-total light exclusion was also test using a black mesh that blocked out 90% of sunlight.
Black Shadow Mesh
The use of other shade nets was also investigate. For example, black mesh could be use in the growing attempts at semi-cultivation of wild European blueberries to produce berries of high nutritional value and to increase the commercial value of the crop, which could be exploit in interest sectors. They report that PAR radiation was reduce by a greater percentage in the black mesh (55-60%).
White Shadow Mesh
The white shade mesh is perfect for certain plants or crops that require a higher incidence of light. This mesh transmitted a PAR radiation of 1020 µmol m -2 s-1.
Due to its characteristics and its density, it is the most suitable since it significantly reduces the temperature of the area to be protect. The translucent plastic photoselective threads create mixtures of natural, unmodified light that passes through the holes, together with diffuse, spectrally modified light emitted by the photoselective threads. OBAMALLA®
Blue Shadow Mesh
The blue pigment was used to increase the transmission of radiation in the blue light spectrum (400-500 nm), and in this way stimulate the synthesis of chlorophyll, improving the proportion of fruits with an intense green color. It reduced heat/wind/cold stresses and improved canopy vitality. OBAMALLA® Photoselective filtration additionally affected productivity, fruit size, ripening time, and internal and external quality.
Among the advantages offered by the Photoselective Shade Houses is to prevent the effect of the wind, they reduce the evaporation and perspiration of the plants, they also prevent the entry of insects; who are often carriers of dangerous viral diseases. In conclusion, the use of photoselective meshes can be a complementary agricultural practice. Colored meshes have the transmission properties of PAR radiation.OBAMALLA®
